SYSTEM AND METHOD FOR A MANUALLY OPERATED VEHICULAR HAZARD WARNING SYSTEM
A road hazard warning system provides a remote control and/or a turn signal-like on-steering wheel activation and engagement device, connected through an electronic interface, to cause a remote device to display a user-selected road hazard message. The device employs a CANCEL or OFF button on the remote control, or neutral position in an on-steering column stalk implementation, and/or an automatic cancellation feature after a given default time period, which provides for the cancellation of the currently-selected hazard and returns the display to a default state.

BACKGROUND OF THE INVENTIONThe present invention relates in general to the existing vehicular signal devices such as taillights used to signal the vehicle's current maneuver, and in particular it relates to a manually-operated visual road hazard warning device attached to the rear of a vehicle and activated from within the cabin by a driver through remote control device, for purposes of warning other drivers behind the driver operating the device of a road hazard that may not be in their visual field.
All vehicles in the United States, as well as in many other countries, are required by law to be equipped with a set of lights in the rear of the vehicle that visually signal to other drivers when the vehicle's brakes are applied, when the driver intends to deviate from straight line motion, when the driver is backing up and when the vehicle's headlights are on. These requirements have evolved over time, often developed in response to traffic safety data. Certainly, they have greatly enhanced the safety of automobiles for their passengers as well as for pedestrians around them.
As the prevalence of the motor vehicle has grown, so has the population affected by their associated hazards. Likewise, their sphere of influence has grown to incorporate an ever-increasing set of common dangers. Brake lights have come to encompass so many levels of meaning, from simply slowing down by a small fraction of one's current speed, to braking hard before reaching a pothole or an object in the road, that it is sometimes difficult to glean important safety information for a particular situation from such an over-used signal.
Other systems have been proposed that use brake tap or stalk movement counts to indicate which one of a set of enumerated messages to display, some have proposed to use a grid of bulb-lit messages and some have proposed to receive, interpret and use the signals emitted from emergency vehicles and from standalone roadside equipment to alert only the operator of the vehicle so equipped of the meaning of the signal. These examples are problematic in their use and/or implementation, or they solve a different problem. The use of brake tap counts presents a very real safety hazard, which trailing vehicles are wont to misinterpret as the operator's intention to stop or slow down, or that they are signaling through courtesy taps that the person directly behind them needs to slow down to provide more road between the two cars, as is the convention. Further, this system is meant to be used in a crisis, and the likelihood of a driver in crisis successfully remembering how many taps to the brakes or clicks of the stalk mean which exact message to be displayed, on top of minding the crisis situation and keeping a tap count is low. It is also worth noting that having to rely on tapping the brakes when the brakes may need to be applied for slowing or stopping may very well create confusion for the driver and those behind him and thus, create more accidents than the system prevents. Systems for integration with a vehicle's turn signal flasher unit suffer from many of the same disadvantages. Additionally, turn signals are known to flash at different rates when components of the system are faulty; this would only serve to further confuse trailing drivers. Bulb-lit displays of previous systems have generally relied on text messages and/or very specific symbols. Reliance on either text or symbols presents a difficulty for trailing drivers. Remembering that the intent is to have all vehicles equipped with such a device, expecting drivers to simultaneously interpret multiple text messages and/or discern symbols from all vehicles in the milieu is not only an unreasonable expectation, but also takes the driver's attention away from the road and thus, again, is likely to cause more accidents than it prevents. GPS and onboard pattern recognition based systems, as well as systems that receive transmitted standard, coded hazard information do not solve the problem of a driver-operated signaling method and device by their very nature.
There is a definite need to extend the current repertoire of vehicular signals to encompass the most common of specific road hazards in a clear, concise manner that can be as universally recognizable as yellow turn signal lights and red brake lights. The present invention solves this need by providing for a manually-operated warning system with a controller used by the driver to select the immediate hazard, and a receiving and display unit that alerts other drivers behind the present vehicle.
BRIEF SUMMARY OF THE INVENTIONThe present invention provides a system, apparatus and method for selecting and displaying a specific visual warning to trailing drivers wherein a specific, color-coded road hazard type is selected from a preset group of hazard categories, causing the selection to be transmitted to and displayed on a display device in the rear of said vehicle until the display is canceled or until the preset display period is reached. Selections and cancellations can be initiated by a user or by an integrated, onboard hazard detection system.
In the case of a manually operated system, the selection and cancellation features are housed with their supporting electronics so as to be available to the driver within his or her reach in the cabin compartment of the motor vehicle, and each input is connected to the signal selector that determines the unique signal to be transmitted. Each specific visual hazard warning selection and the cancellation selection, or action in the case of an embodiment with an integrated hazard detection system, is associated with a unique signal and code.
A manually operated system can have a user interface in the familiar form of a push-button remote control, stalk embodiments including a windshield-wiper like control with movement in a single plane and a neutral position, or a headlight/turn signal-like control stalk with motion in two planes and a neutral position. A side view mirror controller-like rocker switch may also be employed as the user interface.
Illumination can be used to increase usability, such as illuminated buttons on a remote control or the use of a small electronic display on the rocker switch panel to indicate at a glance the current selection. Further, for any integrated embodiment, the currently selected visual hazard warning can be illuminated in a status light on the dashboard display, as is common with turn signals and “Check Engine” lights.
The transmitter and receiver portions of the disclosed invention can operate to communicate over a variety of carrier types and signal technologies, such as over a hardwired connection or via a wireless technology, such as IR (infrared) and radio frequency technologies such as Bluetooth.
Power can be supplied to all parts of the system by a variety of means including deriving power from the motor vehicle's electrical system, from a transformer connected to a cigarette lighter, from an adapter outlet as are becoming common in today's late model motor vehicles or from a common battery pack.
Each of the plurality of selectable visual road hazard warnings, and a neutral display, is associated with a unique signal from the selection and transmission system and apparatus that is in turn received by the receiver and display controller system and apparatus, where it is associated with a specific display configuration that a display controller communicates to the physical electronic color display mounted in the rear window, or alternatively in wireless embodiments on the roof of a motor vehicle in case of a roadside emergency. The housing for the receiver and display include all electrical components and power connections.
Power is conducted into the Fisher Price® logic game module through one or more electrical circuits which comprise one or more warning selection rules, while the speaker and mouse wires are simultaneously disconnected from the base of the Fisher Price® logic game module, subsequently receiving power from a car battery.
Specific examples of components and arrangements are described below to simplify the present disclosure. These are, of course, merely examples and are not intended to be limiting. In addition, the present disclosure may repeat reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed.
